Investigation on different control methods for single-phase DVC

Abstract

Power Quality (PQ) conditioning in LV distribution networks is an increasing concern within modern power system and Smart Grid systems. Several phenomena have classified in standard, among those, voltage sags and rms voltage drifts have been reported as most significant and frequent ones in both MV and LV distribution systems. Several solutions have been proposed to deal with these voltage disturbances. Dynamic Voltage Restorer (DVR) and Dynamic Voltage Conditioner (DVC) are the most promising solutions. Controlling these series connected devices is a challenge especially in single-phase schema which is an appreciated solution for Distribution System Operator (DSO). This paper investigates difference control strategies for single-phase DVC system. Control methods are explained in detail and MATLAB based simulation results are reported. Investigated control methods performance dealing with example voltage drop event have been reported.

Performance Assessment of Series Power Electronic Compensator in a Real LV Network

“…In this context, only electronic compensator devices can be used. Unified Power Quality Conditioner (UPQC) [6,7], Open UPQC [8][9][10], Dynamic Voltage Compensator (DVC) and Series Power Electronic Compensator (SPEC) [11,12], can perfectly cover these long-term events. They have the ability to operate continuously in order to regulate voltage at the point of common coupling (PCC) and protect a group of downstream end users from several voltage disturbances.…”
